Keep this on Hand!By Terrion 5/27/2015

As others have said, this black Egg Crate is very useful, etc...! I keep at least 1 2'x2' square always on hand! Try it, you'll like it!!

So useful!By Alexon 5/15/2015

I have bought this stuff a couple times now and have found so many uses, not just frag racks.

I have used it for Qt separators, covers for qt tank, overflow covers, drying racks for my fish area, and much more.

The black is also really nice, it blends in nicely too. I also like how sturdy it is.

Great product, buy some you will wish you had more because of all the uses you will find for it!

Sadly this is a bit more costly than the white stuff you can get at your local hardware shop BUT who wants white? The black looks much slicker in most circumstances. The packaging was a bit overboard BUT the item was not damaged when it arrived.

Great for frag racks. Black keeps the algae growth down plus looks nicer.

Love the stuff and will keep buying over and over again. Great for frag tanks and it has so many uses your head will spin.

Perfect for a prop tankBy Jasonon 2/7/2014

I use these in my frag tank and at frag swaps. You don't want to have white eggcrate at a show or swap and wash out the coral colors. The black looks great and makes the colors pop. It doesn't seem to be an algae magnet, either. Granted, it's not a cheap solution, but it is one of the best.

I use this for a dozen different things. I bought a 4'X8' piece years ago in a group buy & used it up over the years. I was glad to see this & bought it to have on hand. It's a reefers must have item

Good egg!By Opwanon 1/28/2014

Just as described. This eggcrate is well made and makes your frags grow twice as fast! Well not really, but it is a great product!

I am glad that I purchased these over the white light diffusers. These do not seem as brittle as the white ones. It provides me reassurance that they are not going to break easily.
